I have not seen any previews from Czech tickling in weeks. Their website is still up, but I miss the previews since they have one of the best sites hands down.
If you go onto tickling-submission.com most of the clips have previews attatched (usually indicated by a circle with the play sign in the middle of a picture)
All the Czech tickling previews are now being posted by TMF member Tickle2010; no way to know if Rosando is still personally involved, but the quality of the clips hasn’t diminished in any way.
