No problem! I'm working on a tutorial... here's how I personally add items:
Using Tibia Client 9.61 / Forgotten Server 0.2.14 (Mystic Spirit):
I keep a copy of the current Tibia.dat, Tibia.spr, items.otb, and items.xml in the Tibia client folder, items folder of my server, and the work folders for my item editing tools.. that way, when I'm done editing.. I just copy the latest versions of ALL the files into each of these folders over the old ones... this way I know that my client, server, and editors are all using the same files.. even if, for example, the client doesn't need .otb and .xml files, I copy them all together.. this prevents me from forgetting to update all my programs to my latest editions of the files.
EDIT:
NOTE: The biggest issue with my method is that the three item editing programs I use are sketchy (no offense to the developers, they are EXCELLENT, but not complete), and it's important to be careful to BACK UP FIRST and check for bugs after... there are A LOT OF ITEMS, and, during my process, I encounter a lot of errors, and holes in the arrays, and bugs in general, but, for ADDING items, it seems to work.
