How long ago did you migrate to XF? How did the process go? And what do you and your members think of the change?
Did you lose any features (chat, blogs, gallery, downloads, etc.) and how did your members react to losing them (or did you find replacements and how are they working out)?
How have your moderators managed with the change? Do they find it easier or harder to mod with XF?
Are there any features you really miss that aren't currently available in XF?
How do you find your site's performance compared to IPB?
Have you seen a positive or negative impact on posting at your site since the change-over?
Have you noticed a change in your search engine traffic positive/negative?
Any advice to anyone considering moving from IPB to XF?
