Greetings Fellow SPers,
In order to clear database space to help SP run faster and smoother,
there will be a purge of the PM database a week from today (Monday,
September 20, 2010).
This will only affect PM that is one year or older. If you have such
messages in your Inbox and wish to save them, please do so before next
Monday, after which they will be permanently gone.
Also, now is a good time to delete any dead weight you may have on your
profile. Pictures that have no real use, unfinished pages, outdated or
irrelevant pages, etc.. In short, if you do not need it anymore and it
does not benefit SP's users, please delete it. Until now, deleted pages
have been retrievable in many cases, but this time, they will be gone for
good, freeing up more room in the database.
There will be a reminder about this on Thursday or Friday of this week.
Thank you for your contributions to and interest in SP, and thank you for
any help you can provide in clearing space on the site.
Feel free to comment on this, but this thread will be deleted next week after the purge occurs.
