Can you correct mistakes in your posting?

I do it all the time. I get to typing too fast and realize I made a mistake, but I haven't been able to find a way to fix them. I think most the time people understand the main concept of what you are trying to say, unless there are tons of mistakes. I always reread mine, but there are times I still slip and make mistakes or there are times I just don't worry about it.

Once you have already submitted even if you have not tagged you cannot edit the post anymore. It is therefore important that you preview first what you have written and have them edited before you submit. In my case I always make it a point to read the post all over again before I submit. However, even if I do that, there are times I could still spot some typing or grammatical errors which I really hate. Sometimes I add another comment to correct the mistake in the previous that is the only solution that I know so far.
