HI Jenny, welcome aboard, and be aware that the first few posts of new members are screened to prevent spambots from getting into the site.
So don't get the impression the site is always this clumsy to interact with, posts show up in real time once you're cleared.
Like Krysh said, pics are best but if it's troublesome, there are some questions that can be asked to help narrow it down, such as whether it's acoustic or electric, and the decoration details on the neck and headstock, and also body measurements.
But we like pics even if the owner already knows what kind of guitar it is!
