I think I can translate that:
>> I have just registered.
... at Resource Zone. Obvious! It is his first post.
>> I am an ISP rep.
He says that he is the representative for an Internet Service Provider. I assume the one from the user name.
>> and I wondered if I should ask for a tag.
He has seen that at some other forums, that there are reps. from some companies online, and they have "Rep" or somesuch (instead of just plain "member") under their name. I have seen a forum where JoeAnt, GoGuides, and so on have official reps posting there. He has probably also seen the "member to editor" thread here, and is asking whether as a "rep" he needs to apply for something other than plain "member" too (the answer to that is "no", by the way).
This forum is for people who have submitted websites to the Open Directory Project at dmoz.org for consideration of being listed. The forum is visited by submitters (identified as "member") and editors (identified by their editor type). There is no other member classification here for ISP reps, SEO marketroids, or search engine employees, federal or governmental people, the United Nations, or sentient beings from another dimension.
Ah, Shoot. I've been reading for too much Hutcheson to be good for me.
