How to find a Cabal in TSW
A small bit of cabal-finding advice.
1. If you're interested in PvE, particularly end-game raids/dungeons, go to Agartha and see which cabals are setting up PUGs. If a cabal is kind enough to open up one spot to a new person, they might be recruiting, and it shows that they're at least interested in meeting new people. Also ask folks what cabals seem to be the good and active ones (don't spam chat, just patiently ask around politely). You'll probably see announcements for cabals that are recruiting. Even if you're not ready to run with the big dogs, this will help you identify who the big dogs are!
2. If you're interested in PvP, go to the PvP forum and ask around. If you already have a character, get to the Fusang battleground and ask after cabals there. That's the best place to see who's active and recruiting. Again, don't spam chat, see who's there and then ask around politely.
3. If you're interested in RP, check out the unofficial home of the RP community www.tsw-rp.com. There is a section of cabal advertising there also. The RP forum and/or the Arcadia and Leviathan forums are also useful. (But, from a RP perspective, dimension doesn't matter.) Another good option is to hang out in the Horned God in London for a while and see who's around and talking and interested in striking up a conversation.
4. Unless you're mainly a PvPer, don't limit yourself to just your "dimension". You can bounce willy-nilly between servers, so ANY group of folks that plays the way you want to play is a good choice, no matter what dimension(s) they're on.
5. Verify that the cabal you're interested in seems to have the appropriate number and kinds of members on Chronicle. (You have to determine what that is for yourself, of course.) http://chronicle.thesecretworld.com/ You can look up cabals and players there. A lot of the founding cabals - even the big ones - melted down. Make sure you do a thorough check of the cabal and ensure it's active enough for you. Ask what their last few events were, how many people attended, and how many visit or post on their cabal website.
6. Look for cabals that are actively recruiting either here (TSW cabal forum LINK) or in-game. Some cabals started strong at launch but then melted down, lost interest, or moved on. Be sure that you're looking at people that are currently active.
7. The Secret World Cabal Repository is also a place to search. http://swgrp.co.uk/tsw/
8. Don't necessarily limit yourself to one faction. There are some multi-faction groups that use a custom chat channel for communication.
The Arcane Light PvE and social
KOJO Multigame, PvE and social
Syndicate Serious raiding.
Alea Iacta Est Multigame, PvE and social
League of Monster Slayers Social, grouping.

Good hunting out there, and welcome to the Secret World.
