There are various character limits that apply to posts, comments and replies here on votecitizens.org. This article lists these character limits.
Keep in mind that these limits are measured in HTML characters, which include spaces and formatting tags, so if you paste formatted text from another source, it may contain a fair amount of hidden HTML characters. Pasting text as plain text will help avoid this issue.
