I downloaded the trial version but didn't actually get around to using it before it expired. Examining a copy of a Will I recently got from Cornwall gave me a lead on an ancestor's parents, which contradicted everything that I had found online. This gave me the incentive & the opportunity to try out the program. I did need to keep referring back to the Evidentia tutorials & DearMYRTLE's Hangout's the first time I used it, but after that it was very easy. I can see ways I could use it to build up a case using several sources, which I don't think is really emphasised on the tutorials.
Another plus is that it cost less than $25 AUD (cue another happy dance!).
DearMYRTLE has discussed the Evidentia software on a few of her Hangouts & there are video tutorials and examples on both the Evidentia website and on YouTube.
