Well, this is confusing.
As it might be a good idea it has some downs in it as well, thing about this is basically this server is running on PERP which runs on a database, so it won't be a problem to link two servers to one database and simply run it and let people keep things between servers, but the main problem regarding such a change is the way it affects roleplay, Paralake City is one city, if people can exist in one city but not see the others it is in some way effecting roleplay, maybe
@Xquality can be bothered enough to make a second part of paralake for example and a place you can move to it from one server to another, like some sort of a monorail station, but then again we don't need such a thing for the reason which is simply the community isn't large enough, 4 hours of wait or not the amount of people that wait is pretty small, usually 10.
So some might ask why can't we add more servers slots which I actually recently suggested and it got denied for a simple reason I am able to understand just now, which is the thing that is called the Source Engine, which Garry's Mod runs on, it simply doesn't support such an amount of people in such a customized server in such a customized map, as you can tell by games made by Valve themselves, they also make levels pretty short and you need to load all the time for the simple reason you load another map - because source engine can't support so many details, in fact the Source Hammer(Source mapping tool) limits you on amount of materials, amount of entities, and just limits you on everything, including the size of the map.
This why it might and just might not be a good idea, if it does get up I truly believe you should take care of roleplay(As I offered with the map thingy above) and everything, it just might, somehow, be good for the server, but only if the current server slots gets lowered and both servers will have even slots. making it so if you lower the first server to 50 the newly purchased server will have 50 slots as well(Making it be like a 100 slots server, where you are able to play on different places of the same city), and then again, how can you not move to the other part of the city because there are so many people??? What is that?! Well, you can do like due to the amount of people there is heavy traffic and you are "advised" to stay in this part of the city, hehe.
Anyways, good luck.
