Troubleshooting & F.A.Qs
Are there any limitations for the Description?
Description accepts for 0 to 512 characters long and we do not count whitespace characters. Bear in mind, that while Markdown is a valid input for description, we do not render any markdown elements. We treat it as plain string.
Are there any limitations for the Tags?
Tags are alphanumeric strings, that can be from 1 to 255 characters long. Special characters are allowed. The only limitation is that Tags, cannot have spaces. You can create as many Tags as you want.
