[member="Darth Vyrassu"] - Mind boggling idea incoming for alliances... Like seriously, take a seat on an exceptionally sturdy chair... This suggestion is heavy man, like far out... It'll blow your mind....
Want an alliance? Pitch it in both Major Faction forums.... Have the FA team call council in Skype or a mass PM or such... They can convey through PM or skype the ideas and feelings of the prospective Major Faction(s) they originate from, and hammer out details in the PM/on Skype. When an agreement is reached... And this is where it gets nuts, so you might want to like, buckle a seat-belt or hold onto a wall-stud or like... Nail the chain down.... When an agreement is reached, in order to foster discussion for the Alliance and enable communication and plot planning, etc...You make a minor faction forum to debut the alliance.. Anyone in the Aliiance or interested in particpating as part of the 'coalition forces' joins the new minor faction... Because honestly? Two or more Major Factions with a firm, lasting, and solidified alliance is a pretty damned amazingly powerful thing. And if this ruling goes through... Which I know understand it well enough to be fully in favor that it does go through... I fully believe and endorse you should give up a minor faction slot to participate in it.
Now, for things like say... A sort of PMC type deal, wherein you have exclusivity with a singular faction, but want to retain your 'quasi' independence? The Dreadguard have an awesome example for that... You make/ask for a sub-forum in that major faction... And you conduct personal business there... Darth Praelior I believe even had the Sith Magic sub-boards on the OS forums restricted somehow (I could easily be wrong there, don't quote me!!!!)... So you can possibly regulate access and privacy if... for some reason... You 'needed' or wanted to.... Same can go for Mercenaries.. .Each Major Faction can make a merc board... When they hire you... any coordination with others of your Ilk can be done theri, you have places to plan your unique sub plots, and when you are done, you leave.
As for not being able to be in multiple factions at once to work for multiples of them, or be in two factions at once so you can be a planetary lord and have all of the.... whatever it is you get from that..... I know it sucks... But sometimes, you just can't have all the things, and a few truly minor details have to be compromised on so that everyone is better off.
