It is indeed functional now, except for a couple HTML bugs (Button not working and link appearing white against light grey background) that will be fixed a bit later tonight as another task that required attention came up.
But yes you can follow the instructions now and begin collecting.
Begin collecting officially? Or simbolically, or testnet?
I think you shouldnt tell anyone to start collecting without doing it in an official way. This gives a very unprofessional perception, as no one knows when people can start doing it, until when, how Jinn donators can recollect, should anyone really send real btc even if its a small amount for a testnet?, web with bugs still, etc.. There is nowhere to find all the conditions and instructions on collection.
Marketing-wise this gives a very bad image, of doing things as they come without planning.
Disagree. Everything we've said is happening like we said it. Website went up on the 22nd, as planned, it is functional and everyone can start collecting. The collection process itself is no big 'marketing happening', you can't DO anything with IOTA yet, and you got 90 days to collect it, so collect it whenever you feel like it.
