I'm more than happy to donate but please don't go the ovi route.
It's slow and the payment process has been hit and miss for me and probably others too.

You can be sure you will recieve many emails with people asking; "why can't i buy your app?", "why won't it recognise my card "... e.t.c

The coding competition held on this site had a kind of bounty model for donations. Why not nominate a trustworthy TMO member to handle donations of however much they feel they can give.

In two or three weeks then you should have a fair pot of donations and you would have been free to continue development.

Whatever you choose to do a donation will be coming from me in one way or another. Thanks for your hard work.
