Is there a way to edit comments in D. Tube? With my base Steemit login I can't, and that currently makes D.Tube a lot less serious than YouTube. The Steemit edit functionality going away after 7 days is the same problem. I'm not sure why this is? I've thought it may be a way to temporarily compete without the need for the same storage as the serious social networking players? I'm fairly new to them both, so any info is welcome.
