Jerome, 3 things on SFFS (good to know that it is such an excellent program).
Would be nice to have an email or a web forum. I know the developers have some valid reasons not to bother, but when they do (examples: Online Armor and now GFI Backup and FBackup and Syncback) the user experience can be greatly improved.
This is a bit on the pricey side $40 standard, $70 professional. Thus we would look high and low for the DonationCoder or BitsDuJour discount. Maybe you can mention to Tobias that there are discount realms that are designed for visibility and discussion rather than just penny-saving.
The name Synchronizer tends to make the user think the function is a bit different than backup (I gather it is backup and more - thus the name flexible :-) ). Does this ever get discussed ?
