My wife and I will be continuing in prayer, Greg.
Personally, I have found much encouragement with the brethren via PM. Although there have been a few, occasional disappointing or highly confrontational experiences via PM, most of my experiences with the PM feature here at SermonIndex have been quite beneficial.
For instance, I have sometimes felt inclined to respond privately about certain issues that might not need to be said in a public forum. Sometimes, a believer here may be struggling through a difficult situation and asks for prayer, advice and/or guidance. I have sometimes felt led to share something with them in regard to their potentially embarrassing issue in private since it might not need to be voiced in the public.
At other times, I have been able to set up meetings (by offering telephone numbers or by meeting in person) with some of the brethren as well. Even recently, my wife and I were able to meet with a long-time member from SermonIndex at one of Zac Poonen's local meetings. We have met with other brothers as well. We corresponded and set up meetings entirely by the PM feature here.
In addition, I have sometimes written a response in the forums that I felt inclined to pause and prayerfully consider when and if I should post it. So, instead of immediately posting it, I send it to myself via PM. After prayer, I revisit the post and consider whether to post it, delete it or reconsider the specific words that I used as I felt impressed to do so.
I suppose that all of this can still be done through email. However, the email address that I use here is rarely checked. I used to have another personal email address registered here, but I began receiving quite a bit of spam and even several angry emails in my Inbox associated with discussions on SermonIndex. Because of this, I removed the address to my most often checked email. In fact, I even considered removing any email from my profile.
Perhaps there is a way to list our emails in our profile so that a spam bot doesn't pick it up? I.e. - "johndoe at gmail dot com" instead of "johndoe@gmail.com."
Regardless, my wife and I will remember this in our prayers. May the Lord continue to give you the His wisdom and insight with each decision made regarding the work of SermonIndex. We pray that the Lord continues to bless you and this website...and that the fruit of this labor remains for Eternity.
