Let's say you want to update your pictures. You can always edit your own posts or remove them if nobody has replied, but you may find that your Member Page is getting longer and longer and there's little you can do about it.
Here are a couple of suggestions:
1. Have the entire thread deleted (by me) and create a new page with your updated pictures.
2. Have me remove comments from other members so that you can edit or remove anything you have posted.
3. Have me lock your Page so nobody can post comments. This is not as unfriendly as it sounds, after-all these are intended primarily as a means of enjoying each other's collections and displays, and it will help keep the pages from getting too long. I'll be happy to unlock it any time you want access for updates or changes, or if you decide you do want to allow comments.
Remember, it's your page. You decide how you want it to look. I'll do whatever I can to help you get it there.
