Hi Maddenmb -
In regards to activity history displaying a specific user on the Subscriber Portal -- We had experienced an issue with this feature & removed it while we could work on it. Our developers have made progress on bringing back this functionality & it should be included in an upcoming release.
I pulled up your account to look into the text alert issue you mentioned, but would like to discuss this over private message. Private Messages can be accessed by clicking on the envelops icon in the upper right hand corner of any forums page.
