I would advise against doing more than 1 at a time. We had several working on 2...someone working on 3 and then even somebody working on 4 in this current IRR. Its enough to drive even the most talented among us MAD!
I'm not sure what Terri's rules will be about participating in more than 1 group...see..part of the problem is that if something happens to you and you have to drop for some reason....someone else has to deal with replacing you in whatever # of groups.....a REAL problem. :shock:
