Notice of apology

We recently upgraded this WIX website.  Unfortunately, it appears when WIX did so they deleted numerous photos from our earliest work.  So, you may see a blank rectangle where a photo previously was posted.  We are working with WIX to resolve this problem.  If you run into a missing photo you really wanted to view, email and we'll try to get it to you.

Footnote (2018):  This WIX website was created to preserve photo material from the old Invisionfree (now Tapatalk) forum Let's Talk Seashells when Photobucket announced it would soon curtail its "free" support for image files used in websites.  So, Photobucket material on the Tapatalk site may or may not remain for the foreseeable future.  However, all "new" material is posted only to this WIX site.  We migrated all the photo-based presentations, but still link to the LTS Tapatalk site for some all-text material.  Much of Marlo's material was created in photo formats from PowerPoint slides.  The photos added to this WIX site or copied to this WIX site from Tapatalk are not and have not been edited.  As a result, some apparent links in slides may not work (particularly slides in "galleries"), but look for a corresponding active link elsewhere in the presentation.
