Teams are best when there's a lot of members. If there's... say.. 4 members on a forum. You start modding with 2 or 3 of them.
Chances are, a group wouldn't be formed. Since it's such a small community.
that's how it is here. It's not that active here, and as far as i know, the only official NAMED modding teams have been Biblio-Techa which is the leading team, and it was the first, and well known team. It was for like really advanced modders. Most of the modders are inactive now, and the group title pretty much died out over the past year or two.
When a lot of the younger modders were still around (such as: Masterreys, Zakkifier, myself, Gembo etc) they all were like "PLS LET IN BIBLIO TECHA"
then me and mick joked about forming a team once, but eventually did, in mid 2014. and just look where that went.
in other words, modding teams are likely to die out fast. it's rare in small communities that modding teams make much success.
