A site of which I was a member was literally dying from endless VB5 bugs, including inabilities to logon from various devices and the random malfunction and outright disappearance of many features and functions. The administrator, who had a full time job, couldn't keep up with the avalanche of problems and complaints, and the constant third party IT costs had become unaffordable.
I volunteered to research alternative platforms and costs and to make recommendations for change. After studying various sources, including this site and digitalpoint.com, I recommended a migration to XF. My recommendation was accepted, and I was rewarded by requests to become the new administrator.
To me, that was like asking a tractor driver to pilot a space ship. Fortunately, I had also recommended that we hire an XF expert to perform the migration and become our new web host and service provider. A member here,
@MySiteGuy of Driven 2 Services, was our choice and he has provided excellent service, sometimes with saintly patience.
The journey has been like Dorothy's from Kansas to Oz. Everything works with XF. Nothing is broken. No service has been needed. All costs are way down. All the members happy. No complaints. I've even learned what some of the switches on the spaceship do, sometimes with swift help from this site.
VB -> XF = 0 (brainer)
