OK, as for the templates: go to the template folder (it is within the TB installation folder and called 'templates')
Find the template you want to change. I take MW-Schedule_1 as an example.
Copy (!) the template outside of the template folder: permissions within that folder usually being restricted, plus you want to keep the original.
Use a good editor to open it (e.g. Notepad++ or VisualCodeStudio, which are free, just like Code Writer which comes with Windows 10) but not a regular word processing programme or your standard Notepad which comes with Windows.
You want to tweak the values marked in red in the accompanying picture You need to replace the placeholders, including the exlamation marks, with the actual expressions (which you can mostly copy paste form the workbook)
So line 60: !CONGREGATION_TITLE! becomes North Congregation or Congregation North, or whatever is common in Sranan.
Line 62 !TITLE! becomes the Sranan equivalent of 'Life and Ministry Meeting' or 'Midweek Meeting', whatever you want really.
Then find !SONG!, and replace (Singi). You may want to use 'find' or 'find and replace' function here, this occurs several times. Similarly find !PRAYER! and replace (begi).
Stay away form anything that has more than song or prayer between the exclamation marks.
Line 101 !OPENING! > Beginwortu
Line 116 !GW! > GUDU NA INI GADO WORTU
Line 206 !FM! > DU MUITI FU TR WAN MORO BUN PREIKIMAN
Line 319 !CL! > WI KRESTEN LIBI
Line 379 and 403 !CONCLUSION!> Wan tu lasti sani
You will also want to replace !CONDUCTOR! and !READER! (line 362, 363) as well as !CHAIRMAN! (line 90), again not !CBS_CONDUCTOR! and !CBS_READER!, as the latter are the actual person names you enter.
When done, choose Save as, and choose a name you recognise like MW-Schedule_1_SR.htm, anything will do as long as you retain the MW- part. Then copy (not move) the modified template back into the template folder.
Test and if necessary go back to the file your worked on which is still outside the template folder (that is why you copied, not moved). If you get stuck, come back here.
I can post this particular template tweaked for Sranan, but it is just to show how it is done, since you may be more interested in other templates.
