Even though LyX is a free program released under the GPL, it takes time and money to develop it. Hardware, documentation, domain fees and meetings cost money. Therefore we ask you, the LyX user, to help us make the project go even smoother by giving some help by making a donation.

If you would like, we will put your name up on this page as thanks for your donation. Or you may prefer an anonymous donation.

PayPal

The preferred method of donations is to use PayPal. The PayPal address is donations@lyx.org, or just click the button below.

Sponsorship

As for all non paid work, the development of new feature exclusively depends on the good will of the developers. But we acknowledge that there are some features that are badly needed for some users; this page has been set up to answer this need.

The table below lists some projects with a potential developer associated with it. Each interested developer would use his own PayPal account. He decides himself the minimum amount of money to get the project started. Ideas for project can be collected from bugzilla (search for enhancement request in http://bugzilla.lyx.org) or from the wiki (http://wiki.lyx.org/LyX/FeaturePoll).

Therefore we ask you, the LyX user, to participate in the development of one or more projects by sponsoring them. Another great way to contribute is to motivate the company or organisation you are working for to entirely or partially sponsor the development of one or more projects.

We will automatically put your name up on this page as thanks for your sponsorship. But if you prefer an anonymous sponsorship, please append [ANONYMOUS] to the text entered in the "item" field of your PayPal contribution (see below).

Sponsored development rules

  • All new development happens in trunk (what will become the next stable version), there will be no exception for sponsored development. Back-porting to an older version is of course possible but should happen after.
  • There are no special commit rules for sponsored development, the source code will be evaluated just as any new code, and being sponsored does not mean it has some 'right' to get in regardless of its merit. This item needs to be clear to the involved developer and also to the people or organisation paying for the development.
  • Being sponsored does not mean that the project is reserved to the one who is sponsored. Anybody is still free to do what he/she wants.

Payment

The preferred method of sponsorship from users is to use PayPal -- just click on the PayPal link corresponding to the feature you wish to sponsor. (Note that the PayPal address is different for each developer.). If you already have a PayPal account you can use the PayPal address obtained by clicking on the name of the developer. (replace AT with @.)

In order to correctly identify the project, the sponsor is invited to specify its title in the "item" field of his/her PayPal contribution. There is no minimum sponsorship, any amount of money is greatly appreciated so don't be shy about it.

Companies or organisations are invited to contact the affected developer directly if they want to establish a proper contract. In this last case, listed developers are able to send invoices if needed.

If the minimum amount of money to start the project is not reached and if the developer is not willing to proceed, the collected contribution will be automatically donated to the LyX Paypal account unless the sponsor states otherwise. In this last case, the sponsor is invited to append the [NO DONATION] string to his PayPal contribution. (after the project title in the "item" field.) The sponsor may wish instead that the money is redirected to any other project. In this case, he/she should append the [ANY] string to his PayPal contribution.

These rules are not definitive and we would welcome any feedback or contribution to clarify this payment matter if needed.
