+### Are there any legal issues with AGPL 3.0? Is it safe for me to use?
+
+There is absolutely no problem in using a product licensed under AGPL 3.0. Issues with GPL 
+(or AGPL) licenses are mostly related with the fact that different people assign different 
+interpretations on the meaning of the term “derivate work” used in these licenses. Due to this,
+some people believe that there is a risk in just _using_ software under GPL or AGPL licenses
+(even without _modifying_ it).
+
+For the avoidance of doubt, the owners of this software licensed under an AGPL-3.0 license  
+wish to make a clarifying public statement as follows:
+
+> Please note that software derived as a result of modifying the source code of this
+> software in order to fix a bug or incorporate enhancements is considered a derivative 
+> work of the product. Software that merely uses or aggregates (i.e. links to) an otherwise 
+> unmodified version of existing software is not considered a derivative work, and therefore
+> it does not need to be released as under the same license, or even released as open source.
