Hi Kev - the little crown on your profile pic shows that you have already contributed (thank you!), but I’ve currently got it set that you can only contribute once every twelve months - so on the anniversary of your previous contribution (in June), you’ll lose your crown, and at that point, when you go into your profile, you should see a link to re-contribute.
There’s no need to contribute more often than that - as the costs are adequately covered by everyone’s generosity so far (and contributions remain entirely optional!)
