On this end, I have four dictionaries:
An RTF version of my Phoenix Theory dictionary, which I do not modify
Another RTF dictionary called "Glenz_Fast," where any outlines I find on Facebook or wherever that do not conflict with anything in my main dictionary are stored
A .json dictionary that holds outlines that broke due to a bug I found a few months back which I shared in this thread, complete with screenshots:
I store all those dictionaries in a folder called "Glenz_Plover_Dictionaries," safely tucked away in my DropBox folder ... which basically means those dictionaries get backed up whenever I make a change.
Finally, if you have a few, I share a few dictionary formatting tips -- among other stuff -- in this one:
Sorry about the un-clickable links. Google apparently decided to "fix" the Google Groups, which means we can only use a few fonts and can't create clickable web addresses ... but you might be able to get around that by selecting a link, then right-click it and see if you can open it in another tab.
Hope that helps!
