If you are manually trying to type the spoiler tags out... you aren't doing it right.
Manually: Just insert the equal sign in the first bracket. then if you want a text header for your spoiler, just type in a few words after the equal sign.
E.g:
Automatic: Just go to the advanced mode and click on the spoiler wrap icon in the editing toolbar. Easy peasy from there.
Hi Ryzen, sorry to bother you but I was wondering, in one of you last upload RJ01032786 I noticed that only one track is present, where in DLsite there are listed 5 tracks. Is your upload correct to have just one track? Thanks in advance, and thanks for you work!
