Quote from ORION :

Another thing is...
Every team seems to need a real leader, who acts rather as a motivator than a "leader". He has to keep the pack together
Like a Vykos, a Fordie, a tinyk, and a B11TME

I partly agree, but it also remains the responsibilty of those joing to participate. Unfortunately being an online community makes people less involved/ responsible than they would be irl (although there are enough exceptions).
In 1ST for instance we have 'future' discussions were everybody can add their thoughts and views about what they would like to do racewise and/or like to see change within the team.
Another thing is arranging a meeting irl. Knowing each other irl, and not just computerwise increases the teamfeeling and the responsibilities towards the team. Even tho an irl meeting might be hard to arrange (for instance our members are from different countries) it still will give a boost to the whole team.
You might also consider to talk to those inactive, ask them what the reason is, what their future plans are with regard to the team. If they cannot or don't answer: the removed of inactive members. See it like part of your body (read it as the team) is dead, a arm (read as inactive members) for instance, if you don't amputate that arm eventually your whole body will die (the total team will be nullified - basically this is the point your at now). Although it seems hard to do so it is an essential part of managing a team.

I'd say look at yourself -what do you want - and look and talk to those who are still active - what do they want. Then decide what to do best, a decision you can make by yourself or together with your active teammembers.

Its based on alot of things....I have also thought about kicking out the members that are very inactive etc but i am such a nice guy i would not kick them lol. I would love to keep ITEK running but i dono...Mebe we will take a break or something.

Remember that you've made a name with the team. Quitting now results in the lost of a pretty well known team with a good name. Something you and your members (at least the active ones) worked hard for.
Basically you're now saying that due to you being 'a nice guy' you decide to end the whole team. I'd say kick those who are spoiling the fun for the active members in the team, conitnue with the smaller group to regain the fun you all seem to miss, and try to get some new, fresh, blood. Don't let them ruin your fun. Use the break to think things over

Damn that is sad to hear/ read. Is the inactivity based on the last few months or just now during the holiday season? (I mean the activity of 1ST is also lower since most of our drivers are on vacation).

Anyway good luck and hope to see you all back on the tracks later on.
