Because the domain name of english.stackexchange.com uses an ambiguous word in its first element, I think you should prominently place some sort of “announcement” that anyone coming to ELU can always clearly see.
I say this because most beginners first coming here, including me, always think that ELU must be the best SE site to ask simple questions about basic English, but it is not.
This confusion is because of its domain name of english, and also because we don’t even realize that there is a completely separate ELL website specifically geared for beginners’ questions that come up when first learning English.
When you see a list that includes both english.stackexchange.com and ell.stackexchange.com, it is only natural to make this mistake, so beginners end up asking ELL questions on ELU where they don’t fit well.
I’m moving to ELL now :)
