Excuse me if this is the incorrect place to put this, or if this is a common problem - I didn't see anything about it.
The FAQ says that, if I had already made a Curse account, my MTGS account and my Curse account would be merged. My MTGS account Zhared is still separate from this account. On top of that, logging in with Zhared's e-mail and password on the new site is not working, and I assure you that I have typed the e-mail and password correctly.
Your MTGS and Curse account will only auto merge if they had the same email address at the time of creation.
Fear not you can still merge your mtgs account into your curse account. (will get into that after we get you logged into your MTGS account at least once to make sure you have all the info)
First do this
1) go to http://old-forums.mtgsalvation.com/
2) Sign in with your MTGS username and password
3) go to your profile and see what email is attached there.
4) sign into the new site (this one) with that email and password.
note: if you changed your password on the old site somewhat recently the old one will be the one you can login here wth.
If the above does not get you logged into your MTGS account on this site, send me a PM with the email of your MTGS account (not curse account) and I will do some digging for you.
