In Support Communities how do I see my posts?

In Top Right of screen >. Look for your Avatar

For illustration purposes and have provided a Screen Shot of your Subscription

But, as I am logged into My User Account I can only show mine

Pop Down Menu and look for " My Subscription " which would be in your case, would be yours

You can Edited some of your posting but only and generally only up to about 10 - 15 Minutes after it has been posted

Thereafter - what is written can not be changed

Welcome and thank you too.

There was a period about 1 - 2 months ago, when the older Posting you or I had done were not showing past 6 Days

I know as I do a lot of posting

This was brought to the attention of the " Power that Be "

It has been fixed the last time I looked at My Subscriptions and goes back 3 Months.
