I will play the troublemaker ^^
I voted no, I think it is still fine to have this one year limit, it makes a kind of true "level" to reach in matter of age. It doesn't mean anything ofc, 18 is legal age to drink where I live for example, so lowering the age would be ok.
When I joined OLDA, it was also to be around a bunch of ppl more mature in the TB community. Then, the 19 y.o. limit would have some kind of sense, and the fact that 18 y.o. ppl could enter the circle with the approval of several members is a good thing imo.
Maybe change the 3 days period by something else, because I just find it is too few time to obtain members opinion. Moreover, most of the 18 y.o. members have been brought in by one or two members. Meaning that most members don't know the new comer. Hard to make a decision in that case, maybe let it a bit more time to have the opportunity to meet him/her ingame or inchat, or whatever, and make a preciser opinion.
But if you want to just stick to the drinking legal age limit, than yes, lower it to 18, it is fine by me.
