I've made some updates to the member profiles so that it doesn't take a year for profiles of older members to load:
Blogs Only the last 10 blogs show on the profile, now. There is an added link at the bottom of the bloglist to view a separate page with the full list.
Comments Only the last 10 comments show on the profile, now. There is an added link at the bottom of the comments to view a separate page with 20 comment pagination.
I will probably make other speed tweaks to the website this week. Enjoy!
