Some parts of the forum are broken, unfortunately. Should be fixed soon.
Yes, I agree with the YTS release names that can be problematic. When you upload: Joxxr.2019.720p.WEBRip.x264-[YTS.LT]. The release name gets filled in automatically as: Joxxr.2019.720p.WEBRip.x264-[YTS.LT], but the subtitle itself is stored as: Joxxr.2019.720p.WEBRip.x264-YTS.LT. Hopefully that shouldn't be too hard to fix and accommodate.
oss will hopefully make us aware here when/if it's been implemented.
