ToME: the Tales of Maj'Eyal

Hi, I've seen TOME pop up in lots of bundles and sales lately online. (I've even read about some of them in recent threads, too.) But still, it's unclear to me what the differences are...

If I've donated in the past, do I get something different in the bundle release, or do I somehow get credit? If I install the bundle release, can I still use my existing account? Is there a difference between the bundle installer and the one from te4.org (and which one should I use)? Stuff like that. =)

Here's the link for the IndieBundle.com release:

Damn you stealing my thunder !

In case you get the bundle you can use either the one from the bundle or the one from te4.org.
The difference is that obviously I get less of your money if you get it from a third party, but on the other hand you also get other games
As for how it works, you get a key which you can use to "upgrade" your account to donator (if you alreayd are it adds to the items vault amount)
