I post there all the time. To answer your questions:
DO people who are only on Clomid go there? Yup!
Do you think people who are only on Clomid are welcomed there, or do you really need to be pursuing other types of MA? I think anyone would be welcome there, even if you're only doing Clomid!
As someone who has done or is doing every MA in the book (Clomid, injectables, IVF, ICSI, TESE and IVM just to name a few), I am not offended at all when other ladies join us who are not as "knee deep" in MA. Everyone's journey is unique... what we have in common is that all of us are seeking fertility assistance - whether it's in the form of a pill, an injection, a procedure, or all of the above
I think you would really enjoy it there. It's probably the most fast-paced TTC board after TTC#1.
Hopefully those nice 2 follies this cycle will bring you your BFP though and you won't have to worry about it
