The portal is working fine; there was never a teleport implemented (or intended) for the Arcane Archer's guild, as it's very much a minority group. That said, I can put one in if you like... Add it to my ever-growing list of things to do.
As for the Merc guild, the requirements are that you are either below level 4, or do not have any mage/priest classes. I know, it's finicky and stupid. I'll get around to changing it later.
Also, apologies about the late reply. Holiday season was busy, and it doesn't help that I don't check in here often these days. >_>
