Wait, perhaps you may misunderstanding my suggestion and what Dean/Dynamo have said.

For short term I mean it must be LESS than one month.

And these 2nd VPSes must be returned to the pool for the next giveaway.

This is to ensure that the chance of getting a VPS for new members will not be affected.

Uh.Sorry for this.But if the duration is less for a months things are easier.Current holders can simply ask to "lend" a vps on a first-request,first-get basis just after the monthly giveaway,and return them before next giveaway.
And yes,this usage allows holders to explore more opinions or just resolve an temporily use of vps while not affecting the main one.
