Look up the contact you have, and it will list on the right side of the page who they'll introduce you too
Ah, well that was easy 
Thanks a bunch!
No worries. I didn't find out about the wiki until I first joined the forums about three months after I started playing the game. 
Just remember, not everything for every contact is complete. If you find information, etc. that you can add, it only helps the community as a whole on there.
I've found myself doing a tid bit of editing here and there when I've seen something. Then again, I tend to run Ouro a lot and have caught a few merit changes (some up, others down) from what was written and after a few months of playing caught the wrong coordinates on at least one of the Hollows history monuments. Granted on the latter part, I now have the map pack so that need has substantially declined in its need, but it's still fun to try my compassing CoH using /loc.
50s: Bla- Arch/Mental Cont- Mind/FF, Earth/Cold, Ill/Therm, Earth/Rad Dominator- Plant/Psi, Elec/Earth Corr- Fire/Storm, Arch/Sonic, Rad/Kin, Beam/Sonic, Psi/Time Stalker- Elec/SR Def- Storm/Dark, Emp/Psi, Dark/Elec, FF/Arch, TA/Ice, TA/Elec, Kin/AR, Cold/DP, Traps/Psi Scrap- Fire/Shield Tanker- Dark/Mace, Ice/Kin Brute- Claws/WP, SS/Energy, BS/Elec
I find Red Tomax's table more intuitive. I can scan across at each level range and see the whole contact chain. It's also handy for when a contact gives you a choice of same level contacts, so you can see which ones have the arcs you are interested in.

Sorry if this has been asked but is there some kind of guide that tells you what contacts a contact will introduce you to? Thanks in advanced. ^^
