A simple little blogging tip: if ever you are struggling to get comments to ‘take’ – for example, if before or after you have written a comment the comment box looks like this:
You will usually find that by clicking in the box you will be able to get this:
Before you even try to obtain or click the ‘Post Comment’ box, though, and particularly for a long comment, it is always a good idea to highlight all you have written, and right-click to give you a ‘copy’ option while resting the pointer on the highlighted text. Very often, this action alone is enough to clear the system, and the comment will then go through. If not, and either you lose it or lots of nothing still happens, refresh the page and use ‘paste’ to try again.
If it still fails, try another browser.
Either way, the action of having taken the copy means that you won’t need to re-write the comment.
It is, in fact, a very good habit to ‘copy’ all longer comments before you try to post them.
