Hi, It’s been a while since I haven’t logged in to Wikipedia, and I just noticed you had reverted edits I had made in March ’17 on the Smallworld page, considering it was vandalism. Well it wasn’t. I have worked with Smallworld since 1992, and share with my colleagues of the time a knowledge of the company’s history that is certainly as good as yours. I don’t remember what my edits were at the time, but it was certainly to correct some error or to add precision. In the future, please contact me before deleting my contributions.
