General Starting Grappling/Etiquette

[Pro Killer]

So Im thinking about starting Grappling, The place I've trained Muay Thai for a year or so offers classes, They offer:
Wrestling one evening and MMA another evening.
The Wrestling has a good reputation with the instructor being a former National Open Freestyle Champion and Runner Up/ 3rd in different years, + Has trained at the Olympic Traing centre and also has won local MMA tournaments and has good kickboxing/boxing records but as he's a grappling instructor Im just focusing on that.
Good pedigree and has a good reputation amoungst other schools.

The MMA has a poor reputation, I've seen our fighters win in local shows but the consensus is that you learn more rolling with people than the actual instructor's teachings (I don't know if thats a problem) as the Muay Thai doesnt have a good reputation either but we've produced local champions and I actually do this and know I've learned alot of legit stuff in Muay Thai. The instructor has trained BJJ in Thailand at Tiger Muay Thai and thats what the general class is I am lead to believe. You just combine your Muay Thai with this groundwork and thats "MMA".

So firstly I don't know which one to go for, Looking for opinions and then I'd like to talk about Etiquette as I don't know about what's the unwritten rules are or anything.
Firstly these classes take place after the Muay Thai so obviously people will be sweaty, Should a change of clothes be taken??
Then I've heard about ringworm, I'd guess you need some kind of underarmour?? as I wouldn't like to roll with someone just wearing boxers and Thai shorts.
I think that's it really unless theres anything else you need for Grappling?? It's obviously no Gi class and I don't think they wear singlets in the Wrestling either.
I have consulted the FAQ but theres nothing really about the "Unwritten" Rules when starting out, Just advice on styles and techniques!
Thanks

cut your nails, wash your clothes, take a shower, and be nice. Grappling Etiquette is the same as normal life etiquette.

It sounds like your school would be a decent place to start. If you get to the point where you wnat to learn more, check out other schools. If they have produced a handful of local talent, you should be able to learn some decent stuff at least for a year or so. in our nogi class we wear tshirts and shorts.

Worried about buggies? Make sure the mats get cleaned after class, and if they don't, offer to do it.
