Although not against any rules, it is generally considered "bad form" to post on an old thread with a current question (this thread is 16 months old), but much better to start a new thread. Just sayin'!
IMHO it is 100% safe to play at the MainStreet Group. Just be aware their cash-outs are not the quickest.
Also check their bonus terms very carefully - if you are not in the USA or Canada they have a VERY bizarre rule about playing slots

{Edit} Ooops - just noticed you are in NY. So you can ignore that last bit!
