Great tips in previous posts! Another idea is to take a small pocket size note pad with you and jot down names, places, tidbits as the day goes along. In my advanced age

, I find it hard to remember some of the finer details until after I've already posted! Also, when we get back to the room each night, if I'm not too tired, I will add some more thoughts about the events of that day.
After the trip, when we get back home and I start writing the TR, I do a rough draft in a word processing software like MS-Word. I like to write it down, wait a day or two and then go back and reread everything. I always find something I left out or something that needs to be clarified or something simple like a misspelled word.
Once you are ready to start posting, you can copy and past sections from the rough draft directly into your post. Then you can insert pics as needed. I always hit "Preview Post" too so I can make a final read.
I use Photobucket to store my pics. I make separate albums for each trip so they are not all mixed up together. When uploading pics, you are given the chance to name each pic before you hit "Save and Continue To My Album". I give each pic a number in the order of when I will be posting them in the TR. That way I know where to find them easier. You will probably not upload all your pics at one time so even by numbering them, they will not be in order. Just select the "Organize" option in Photobucket and sort them by Title. If you numbered them like I do, they are then all in numerical order.
When I get ready to insert a picture, I just move my cursor over the pic to post and a window will pop up like this one...
Once that pop up window is there, move your mouse cursor all the way to the bottom of the pop up and put it over the info to the right of "IMG code". Left clik your mouse once and you will briefly see "Copied" in that space before it returns to the original info. It has copied the link to that specific pic for you. Then toggle back over to your DISboard post and paste the link into your TR where you want it placed. By copying IMG code, you do not have to put the
tags on either side of the link, they are already there.
Finally, you can put a link to your TR in your signature so others can go to it directly from your post in other places. As you can see, I have 3 TR's linked in my signature.
Those are my 2 cents worth for what it is worth. A TR is a labor of love but I enjoy doing it. Hopefully others will get some enjoyment out of it and learn a thing or two. I know I have learned a lot by reading other DISboard members TR's. Have fun!
