I think that Andy is done.

People grow, people change, people sometimes need a shift, sometimes things happen in life that either hold one back from something or compel one to move on to other things.

I do not sense the same level of interest, activity, or passion. Good for him if it is not unchosen, following your passions and moving on must be paramount in a person's life... not so good for us though. Oh well, the world turns.

This forum and indeed the product itself are likely not long for this world.

I don't know what happens if AR Vitae is pulled from the store (on transfer of IP, sale of company etc.) , I have a good old copy of AR6 which will always work, completely oblivious to app stores or software managers or accounts of any kind.
