Hi Dan, the forum is the perfect place for asking advice about clubs & courses worth playing from other local members (including likely costs, benefits, how friendly they are etc). The course directory is more about providing members with a general resource to decide where they'd like to play and, unfortunately, maintaining the detail with waiting lists and prices for joining a specific club is not something we think would prove of major benefit to enough members, but we could be wrong! So let's see if anyone supports your suggestion in this forum thread.
With regard to your objective of playing more joining a golf club - to help best you'd need to tell a bit more - What particular area would best suit you? What type of course do you prefer to play (parkland, tight, open etc)? What are you looking for (friendly club, cheap club, challenging course)?
Alternatively, to meet more people and play more golf you could post more games/join more games on TSG - it's what the community is for !!!
PS, nearly 50% of all TSG members do both - member of a spceific club for competitions/member of TSG to meet new golf friends, play alternate golf courses and have more fun.
