Hi MelodyCat!
Congratulations, you've come to the right place!
I am one of the veteran PNAMs here at GC. In case you are wondering "PNAM" stands for "Potential New Alumna Member".
There are loads of people here who can offer you advice and support and cheer you on while you go for it.
The fact that you previously pledged a MCGLO is irrelevant in my opinion.
Please do browse through this forum and check out the various threads regarding AI. CutiePie2000 has already given you links to some of them.
In addition, there are a handful of people like me who are more than happy to discuss this with you in private if you like. Please do not hesitate to PM me if you have any questions or just want to chatter away about it!
PNAM,
.....Kelly
