The main one anybody should ever have to deal with is if a link is included in the comment. As 99.9% of all spam contains a link where one either gets exposed to an ad or something worse if it is clicked upon, the programming for this site is set up so that I have to approve any comment containing a link before it will appear on this site. I apologize that such comments (which I highly encourage to exchange important and/or fun information) will be delayed until I can be at my computer to OK them. However, until WordPress can program a better system or I can find a suitable plug-in for their software that is effective and user-friendly, I believe all will understand that a delay in having a comment containing a link appear here for everybody else to read is better than having any spam.
As for regular comments that do not contain a link, those should appear within seconds after being submitted.
On a completely different topic…I don’t really like to be cryptic or seem like I am superstitious but I don’t want to jinx myself. Let me just say that I hope to have some very good personal news to share within the next several days — something that came completely out of the blue less than a day before I had to make some huge and unchangeable decisions about my future. Stay tuned as my next entry could very well be filled with elation…or, some of the best cussing I that have engaged in online in quite some time. >:-)
