Hey there
@ZOS_GinaBruno !
This is a "multilateral" request (some part UI, some part game-mechanics etc) so I'm addressing you instead as you are community Queen

I'm one of all who (co-)lead a guild and have decided to shed some light upon ESO lack of communication tools, not intra-guild but inter-guild wise.
This is the situation of the game atm:
If you would like to create a coalition/collaboration/alliance/pact etc with another guild. The only options are:
- Merge.
- Create an additional guild where all guild members from each guilds can join to access a mutual chat channel.
- Appoint 'match-makers' in each guild, acting as chat-chains.
- GM, Officers, or members apply for membership in the coalition guild and act as a vis-a-vis channel.
This is a rather massive problem for some guilds atm. Why not add the option to create
custom chat channels, open for anyone through invite or a slash-command?
By doing so, the issue of already having 5/5 guilds, the peer-pressure for these 'match-makers' and the politics surrounding a merge could easily be avoided.
I mean, plenty has got TS/Vent etc. But it would be so much more convenient and accessible if there was an option in-game that provided a chance of creating a joint-chat channel bor both (or more) guilds.
Thanks for the best MMORPG so far.
I would hate to see ESO leaving, and I love to see it grow.
