The current blogging software I use on this site does not provide for email subscriptions, but if you do not use RSS feeds or know what they are and would like to be notified when new posts are added here, just the the Contact option at the top to send me and email saying you want to subscribe and I will send you an email when new posts are added.
When you subscribe I will send you an email to confirm that subscription. when you receive it, simply reply to the message and I will know it got through and the email address is correct. If you do not receive that message within 48 hours, it can be due to spam blockers trashing the message before it gets to you. You might look into your Spam or Junk folder and see if it is there. When you find the message, if you add the email address I used to send it to you, to your contact list, it may make the messages no go into the spam folder depending on the email you are using.
For some reason, Yahoo! email has really harsh spam filtering and if you use a Yahoo! email address to subscribe with it can take days, weeks and sometimes still not make it to you. If you have any other email address that you regularly check, it would be best to use a different one.
