A lot of guild members have more than one character they enjoy playing. We currently have no limit to the number of characters a member can have in the guild, all we ask is that you ensure all of your characters are linked in the roster notes. This should be indicated by stating <"Main Name" Alt>.
A members "main" character is generally the character they first joined us with. It doesn't have to be the character they play the most, or even at all, it is simply the first to join the guild. A member's "alts" are any additional characters that have joined subsequent to the first. Each of the additional characters should have a public note in the roster stating that is it an alt of the first character to join.
Should a member remove their "main" character from the guild, or rename it, then they can ask for an alternative character to be classed as their "main".
"Main" and "Alt" characters are treated exactly the same in the roster, with the same rules for promotion and inclusion in the guild and guild events. There is therefore no reason to switch which character is shown as "main" in the roster.
If you wish an alt to join the guild, simply whisper someone online in the guild from your alt, asking for an invite, referring to your "main" character name, or use the /guildfinder to "apply" from your alt, making sure to mention your "main" character name. If you use the Guildfinder, please do remember to accept the invite as soon as possible.
Please do ensure that all of your characters are linked via the roster notes. You can do this either by asking the GM or an officer to amend them, or do so yourself (please note that in order to alter your own notes, you must be logged onto the character you're amending). This is partially because, when you reach "Wolf" rank with any of your characters, all your linked characters are promoted to Wolf Alt, and partially because characters that don't appear to be linked to an active member are likely to be removed from the guild for inactivity.
We do not, as a rule, generally change the "main" and "alt" designations for any other reason than if the currently designated "main" leaves the guild/is deleted. If we do it for one, we have to be seen to do it for all; many people have many alts; some people switch which character they consider their "main" on a fairly regular basis. All this stacks up to mean that, if we started changing the "main" character for people, it would involve a lot of admin, changing links in our guild management addon; changing all of the alt notes in the guild roster; changing discord nicknames, etc - every time someone decided to play a different character for a while. Life is too short for that.
If people wish to be "known as" a different name, then we encourage them to use an addon such as Incognito Resurrected. You may, if you wish, place the name you wish to be known by, in the public roster notes against your "main". Please do not include any other information. Any information deemed inappropriate in public notes will be deleted. Persistent offenders amending their notes inappropriately run the risk of being removed from the guild.
